ALUMINUM ROLLING PIN.

Application filed November 11, 1920, Serial No. 423,422. RenewedDecember 24, 1921. Serial No. 524,743.

To all whom t may concer/a.'

Be it known that we, HARRY E. KEER and EDWARD C. AHLHEIM, citizens ofthe United States, residing at Cleveland, in the county of Cuyahoga andState of Ohio, have invented certain new and useful Improvements in anAluminum Rolling Pin, of which the following is a specification.

rIhis invention pertains to an improvement in an aluminum rolling pin,and our object in making the rolling pin as shown and hereinafterdescribed is to simplify its manufacture and assembly and reduce itscost of production to a minimum, having in mind also a durablearrangement and union of parts adaptedto provide smoothly finishedsurfaces and tightly closed joints to promote cleanliness in itsdomestic uses and to establish a rigid bearing for rotatable handles atopposite ends of the pin body.

In the drawing accompanying this application, Fig. 1 is a longitudinalsection oi my improved aluminum rolling pin, and Fig. 2 is a sideelevation thereof. Fig. 3 is a sectional view of the aluminum body and aside elevation of one end cap and trunnion afliXed thereto. Figs. 4, 5and 6 are side views of the end nut, trunnion and end cap, respectively,and Fig. 7 is a sectional view of one of the handles.

The round cylindrical body of the rolling pin comprises a smoothseamless tube 2 of aluminum having internal screw-threads at itsopposite ends. A dished end cap 3 of aluminum having a rounded borderflange 4c of the same diameter as tube 2 is screwengaged with each endof the tube, and when a tight joint has been effected the cap is lockedin place by a small pin 5 passing through the body into the screw flangeof the cap. The concave-convex end wall of each cap 3 embodies a shortround hub 6 having a central screw-threaded opening 7 adapted to receivethe reduced screw-threaded end 8 ot a short steel stem or trunnion 9 forthe round handle 10, and each end of this handle is counterbored orprovided with an enlarged recess 11 as compared with its longitudinalSpecification of Letters Patent. i

counter-bore or recess fits and rotates on a round extension or boss 18of a rounded nut 15 having a blind screw top for the outer reducedscrew-threaded extension 16 of stem or trunnion 9.

The main bore 12 of handle 10 is slightly i larger in diameter thantrunnion 9 and therefore the handle is supported rotatably only at itsends with a minimum of frictional contact, and it rotates freely,although the end joints are relativelytight and snugly iitted to avoidaccumulation of dirt. The respective closure caps, trunnions, handlesVand nuts at the opposite ends of the tube are constructed alike andmade separable from each other and the tube, and may be easly replacedor repaired if bent or broken, and disassembly of the parts at one endmay be effected without disturbing or affecting the parts at theopposite end of the tube. Y

What we claim, is:

1. An aluminum rolling pin, comprising a smooth aluminum tube havingseparate endclosure caps screw-engaged therewith, each cap having a huband a. projecting stem, a nut having a boss aiiXed to the outer end ofeach stem, and ahandle rotatably supported upon the respective hubs andbosses associated with said stems.

2. An aluminum rolling pin, comprising a seamless aluminum tube,separate aluminum closure caps pinned to the opposite ends of said tubehaving round hubs, separate trunnion members: extending from and rigidlysecured to Said hubs, screw nuts having round bosses engaged with theouter ends of said stems, and round handles sleeved over said stems andcounterbored to rotate upon said hubs and bosses.

3. An aluminum rolling pin, comprising a seamless aluminum tube, dishedand screwthreaded aluminum caps adapted to be afixed to the oppositeends of said tube, separate steel stems screw-engaged with eachy cap, anut sereweengaged With the outer end of each stem, and a round handlesleeved upon each stem between a eap and nut.

4. An aluminum rolling pin, comprising an aluminum tube having separateend-c10- sure caps aixed to the opposite ends of said tube, each caphaving a. hub and a projecting stem, a nut having boss aixed to theouter end of each stem, anda handle rotatably supported upon therespective hubs and 10 bosses associated with said stems.

Signed at Cleveland, in the county of Cuyahoga, and State of Ohio, this8 day of November, 1920.

HARRY E. KERR. EDWARD C. AHLHEIM.
